Nelson, Royal Oak, Mich, assignors to Harry Mich, a corporationApplication April 11, 1949, Serial N 0. 86,752 Claims. (01. 9753) Thisapplication relates to a plow and more particularly to a disc plow,which may, if desired, be connected to a tractor.

A disc plow during operation tends to move laterally of its intendeddirection of movement A further object is to provide improved means in adisc plow for restraining and controlling its lateral movement, wherebythe plow may be concapable of limited lateral movement and so permitslimited lateral movement between plow and tractor.

Another object is to provide an improved plow on which the number ofplowing elements may be readily increased or decreased as the occasiondemands. Such a plow may be of the disc type Fig. 7 is a detail viewshowing a furrow wheel and its mounting.

Although the invention is susceptible of various modifications andalternative constructions and tirety in Figs. l-4, inclusive, wherein itis designated by the reference character 26. has a longitudinal beammember 2!, which extends in the direction of the longitudinal member 2iand terminates in a depending portion 23. As shown in Fig. 13, the tailmember may be of hollow construction and has a tubular front end 24,which extends into the rear end of the beam 2| to close the same and inassembly provides a smooth pleasing continuation of the beam member 2|.

24 of the tail member 22. This front portion has transverse tubularbridges 28, through which the bolts 25 extend. The front end of the beam2| is closed by a cap 29. An upwardly extending bracket 30, which isshown by way of exam plc to beef hollow" triangular shttp'f-lssectrrflas by welding, to the top of "beam 2| near its front end and atransverse bracket 3| is secured similarly to the under side of the beam2|. A cross shaft 32 with offset ends 3 3 is clamped by U-bolts 34 in agroove in the lower side he transverse bracket 3|.

The bracket 30 and the ends 33; of the cross shaft 32 provide threeproperlyf'spaced 'pp" is for attachment to the rear ends" of thetriangular arrangement of hitch links found in certain commerciallywell-known tractors? "These ,conn'ec tions are through ball joints sothat these links.

will permit limited lateral movement of the" plow" 2 with respect to thetractor.

The furrow wheel comprises a disc 50 (Figs. 2-5) to which issecured a member 5! presenting an outer donlal;'surfa'e" being adaptedto limit penetrati'bfibfth disc in the ground. The disc 50 andassociated member 5| are journaled upon sfpart 52, adjustably secured toan arm 53, as and 11.

Before the cap 18 is applied, closures 79 having legs 80 areapplied to the openings in the beam previously occupied by the bushings21. Upon application the legs 813 are straight and are inserted throughthe beam openings from the outside. Then the legs are spread, as shownin Fig. 16, so as to be brought against the inside of the beam, byoperations performed from the inside, access being had through the openrear end of the beam 2|. Then a hook end 8| on a rod 82 is inserted inan opening 83 the beam 2|.

The cap 29 may be secured in similar fashion to the front end of thelongitudinal member 2|.

Now the assembly comprising bracket 62, arm 53, spring 61, links 68,part 52, scraper 58A, and furrow wheel 50 is detached from the plate 38on the tail member 23 and is applied to the rear side of the plate 38 onthe hanger 37, as shown in Fig. 15.

The relation of the furrow-wheel axis formed by the transverse end 59 onthe arm 53 to the intended direction of movement of the plow is the samefor the two-disc plow as for the three disc plow. The furrow-wheel axisis inclined generally transversely of the line of movement. The leadangle of the furrow wheel may be kept The reverse of the aforementionedprocedure .is followed to reconvert the plow to three discs.
